A University of Idaho graduate who became a nationally recognized wellness expert is premiering a documentary about his life this week at the Kenworthy Theatre in Moscow. Ben Greenfield, who now lives in Viola, has spent more than 20 years studying biohacking and wellness. It led to him becoming a nationally renowned performance coach, which spawned a successful career in podcasting, writing and consulting. Greenfield was born in Lewiston and studied at Lewis-Clark State College and the University of Idaho. He said this idea has gone mainstream in recent years largely thanks to its popularity on social media.
